Scientists Thrilled to See Layers in Mars Rocks Near Opportunity AScribe Newswire

New pictures from NASA’s Mars Exploration Rover Opportunity reveal thin layers in rocks just a stone’s throw from the lander platform where the rover temporarily sits. Geologists said that the layers — some no thicker than a finger — indicate the rocks likely originated either from sediments carried by water or wind, or from falling volcanic ash. “We should be able to distinguish between those two hypotheses,” said Dr. Andrew Knoll of Harvard University, Cambridge, a member of the science team for Opportunity and its twin, Spirit. If the rocks are sedimentary, water is a more likely source than wind, he said.
